Survivor

This will probably sound pretty boring (it's not), but here goes nothing. Mary Winslow has powers that no one can believe for a ten-year-old. She suddenly gets stranded on an island because her parent's ship sunk. She has to try to find her parents and discover more about her powers, but while on the island, she meets an interesting child named Mary. Coincidence? Maybe... Fate has a strange way of working out.
